Definition
The term entered internet perfumery vocabulary in the mid-2000s, spreading from makeup community usage ("dupe" for a more affordable alternative to a luxury product). In niche perfumery, dupes occupy a contested ethical position: enthusiasts debate whether they democratize access or undermine the creative and economic viability of original houses.
On Osmetheca, dupe information is consolidated in the FAQ section on dupes and controversies; individual perfume entries do not list dupes to avoid misleading associations.
How it works
Dupes exploit the fact that olfactive compositions cannot be trademarked: the scent of a perfume is legally unprotected in most jurisdictions, only the name, bottle design, and formula documentation are. Brands such as Dossier, Zara, Montblanc (for mainstream), and numerous Arabic houses produce formulas explicitly described as "inspired by" reference fragrances (Basenotes wiki, accessed 2026-05-27).
The quality spectrum is wide: a competent dupe may replicate the dominant chord of a reference fragrance while using lower-grade or synthetic substitutes for expensive materials; a poor dupe shares only superficial similarities. Niche collector communities actively discuss dupes on Fragrantica and Reddit, where they serve budget-conscious enthusiasts who want access to an olfactive profile without the full-price commitment (Reddit r/fragrance, accessed 2026-05-27).
